1.Butter gives the authentic taste and flavor to this recipe,if you don't have butter you can add ghee but definitely do not add oil to toast the sandwich.
2.you can ad thinly sliced beets along with other veggies.
3. Here I have grilled the sandwich for a short time. If you want your sandwich crispy you can grill till they become golden brown.
4. Do not miss to sprinkle chaat powder and pepper powder over the veggies as they really add a zing
